Definitions

  • the invention relates to a traction motor in electrically or diesel-electrically driven vehicles, the traction motor mounted in a housing being grounded.
  • the traction motors are fed either directly from a network or via a converter with power electronic actuators.
  • the housings of the traction motors are grounded via a ground wire in the electrically powered vehicle. Due to the common mode voltage (zero voltage) in the traction motor, which is principally caused by an inverter, and the sudden voltage changes at the terminals of the traction motor, capacitive currents and arc discharges occur in the parasitic capacitances in the traction motor and in the bearings of the traction motor To store.
  • insulated bearings or insulated bearing bushes prevents the classic shaft voltages, low-frequency or DC operating currents and, in particular, reduces converter-related capacitive bearing currents and arc discharges in the bearing.
  • the disadvantage here is that the insulated bearings have a very high purchase value and a relatively sensitive one Require installation in the drive so that the bearing insulation is not damaged. This must be confirmed by an additional check of the insulation after installation.

  • the invention is therefore based on the object of providing a grounding for a traction motor which avoids the disadvantages mentioned above in a simple manner.
  • the task is solved in that the housing of the traction motor is grounded via a capacitor.
  • the insulated bearings can be replaced in whole or in part by the much less expensive electrically non-insulated bearings and the protection of the bearings against damage from stray currents is ensured.

  • a capacitive voltage divider acts between the parasitic winding housing capacitance and the capacitance of the capacitor between the housing of the traction motor and vehicle earth, e.g. Bogie parallel to the air and storage capacity. If the voltage at the bearings, ie the voltage across the capacitor, does not exceed the dielectric strength of the lubricating film in the static case of 0.5 V or in the dynamic case of 2 to 10 V, the lubricating film acts as an insulator and thus prevents capacitive Bearing currents and arc discharges.

It is particularly advantageous if the bearing voltage is monitored in each of the embodiments listed, ie is used as a measurement variable for the functionality of the capacitor. In the event of a fault, the bearing voltage rises, so that a signal is set that clearly establishes an assignment to a faulty capacitor.
